Computer Graphics, Fall 00

Thomas Funkhouser

Assignment 0: On-line Enrollment

We want to make a web page with a photo of everybody taking the class, so we'll need a capture of each student. This helps us get to know you, and helps you get to know each other. Furthermore, we would like you to web-publish a photo along with your responses to the Questionnaire below.

Follow these steps to obtain and publish your photograph:

  1. Log into one of the MECA SGI indigo2 workstations (E-Quad, room E423).

    2. pixel.gif (42 bytes)
  2. Run videopanel from the command line prompt.

    3. pixel.gif (42 bytes)
  3. Make sure the following are set:

    4. Def. Input: IndyCam
    Input Timing: NTSC
    Sync: Internal.
    pixel.gif (42 bytes)
  4. Run capture from the command line prompt.

    5. pixel.gif (42 bytes)
  5. Click on the Icon of a face in the bottom left corner and select Snap Image From... and choose IndyCam.

    6. pixel.gif (42 bytes)
  6. A real-time image should now appear in the window. If the image is black, make sure the sliding camera shutter is open!

    7. pixel.gif (42 bytes)
  7. If the image is dark or strangely colored, return to the videopanel window and on the Pro menu select IndyCam->Signal Controls. Try holding a white piece of paper up to the camera and hit the White Balance button. You may also play with the color sliders.

    8. pixel.gif (42 bytes)
  8. Adjust the tilt of the camera to get your face centered and twist the lens to achieve focus.

    9. pixel.gif (42 bytes)
  9. Now return to the capture window and from the Tasks menu select Show Task Settings->File Format->Gif.

    10. pixel.gif (42 bytes)
  10. Punch the record button (red circle in lower right) when you like the picture. Smile! This saves a file in your home directory with a name like capture.gif.

    11. pixel.gif (42 bytes)
  11. Place a copy of this file into your public_html directory in the directory public_html/cos426 on your CIT account (not your cs account). See the note below for details.

    12. pixel.gif (42 bytes)
  12. Test out that your picture is successfully published by sending your web browser to http://www.princeton.edu/~yourid/cos426/myface.gif. See note below if you encounter problems.
Note: If you have never set up a WWW home page before, you'll need to make sure your home directory, public_html directory, and files in public_html are world readable. You will do this in your CIT account on arizona.princeton.edu as follows: 
% cd
% mkdir public_html (if you don't already have one)
% mkdir public_html/cos426
% cp capture.gif public_html/cos426/myface.gif
% chmod 755 . public_html public_html/cos426
% chmod 644 public_html/cos426/*
Copy the following questionnaire into an E-Mail message, fill it out, and e-mail it to Misha Kazhdan (your T/A) at mkazhdan@cs.princeton.edu. Please put "COS426 Questionnaire" in the subject line of your e-mail.
